In Young’s experiment, the distance between the slits is reduced to half and the distance between the slit and screen is doubled, then the fringe width

View answer and explanation

Correct option: D

Will become four times

Option D (Will become four times) is correct because the fringe width is directly proportional to the distance between the slit and screen and inversely proportional to the distance between the slits.
